APPARATUS FOR REMOVIN SAND-BARS, 8 0., FROM RIVERS AND HARBORSL SPECIFICATION forming part of Letters Patent No. 284,387, dated September 4, 1883.

Application filed May 21, 1883. (No model.) I

To all whom, it may concern:

Be it known that we, OLIVER H. 1?. 00B- NELIUS and GEORGE HFTURNER, both of Turner, in the county of Marion and State of Oregon, have invented a new and Improved Apparatus for Removing Sand-Bars and other Obstructions from Rivers and Harbors, of which the following is a full, clear,and exact description.

Our improvements relate to apparatus for removing sandbars, accumulations of silt, and similar obstructions to navigation in rivers and harbors, by the action of a stream of water f discharged upon the obstruction for loosening it up, and-the creation of a rapid current for distributing and carrying off the loosened materiaL- y The special-objects of the invention are to accomplish the work with as little expenditure of power as possible, and to provide apparatus that can readily be used in shallow waters and in waters where snags and drift-wood abound, without risk of injury to the apparatus.

Reference is to be had to the accompanying drawings, forming part of this specification, in which similar letters of reference indicate corresponding parts in all the figures.

Figure 1 is a sectional side elevation of a vessel provided with our apparatus. Fig. 2 is a section in larger size of the tube and wheel. Fig. 3 is a perspective view of the wheel, and Fig. 4 a detail view of the tube-joint.

The vessel A is providedwith a propeller, a, for its propulsion. In the bottom of the vessel is formed a longitudinal well or recess,

b, open atthe under side and closed at the top. Near one end of the recess, and projecting in aninclined direction through the bot tom, is a trunk, B, the upper or rear end of whichis closed by a suitable cap, the lower or forward end being open and terminating within the recess. At the under side of the trunk B, and opening at the rear, is a flaring.

mouth, 0, and within the trunk, below the mouth 0, is a wheel, d, upona shaft, 0, which extends through the cap of the trunk into the vessel, where it is connected to an engine or' engines, f, by which the wheel is rotated.

D is the hydraulic tube, connected to the top of recess 1) bya hinged joint, 9, and lapping over the lower end of trunk B, so that the tube may swing vertically without openarrangement the tube can be raised or lowered to a proper position for operation, and when not in use can'be drawn entirely into the rethe way of snags or other obstructions. This allows the vessel to be moved from place to place without danger of injury to the tube from the bottom in shallow waters or fromobstructions. At the mouth care bars m, forming a grate, that prevents drift-wood or other material from entering.

The wheel d maybe of any suitable c011- "struction; but as shown it is formed with in clined paddles or wings held in an outer rim, and is fitted between fixed disks n,having openings between guide-flanges 0, that serve to direct the water to the wheel and counteract rotary motion of the water inthe trunk and tube.

In theoperation of the apparatus the vessel is to be brought bow onto the bar, the tube then lowered, and the wheel set in motion. The action of the wheel is to draw the water in at the mouth 0 and discharge it in a powerfulstream at the mouth of tube D, thereby loosening up the sand or silt, which is carried away by the current thus created, assisted by whatever natural current there may be. The propeller a is to be rotated at the same time to counteract the reactionary effect of the stream of water on the vessel. The apparatus being at the bottomof the vessel, the wheel has a solid body of water to act upon, and as the water has to be raised only a short distance, and never above the surface, a powerful stream can be forced through the tube by the expenditure of comparatively little power.

5 In place of the wheel, as shown in tube B,

an ordinary propeller-wheel may be used; and we prefer to use for rotating this wheel or propeller two engines,working on a single crankpin and set at right angles, so as to overcome 5 cess b above the bottom of thevessel, out of dead-centers and insure a more steady motion.

Having thus fully described our invention, We elalm as new and desire to secure by Let ters Patent the wheel. d on shaft 6, in combination with the swinging/hydraulic tube D, lapping the trunk, hinge-j ointed to it at g, jointed at h to swing laterally, and adjustalolyv suspended by v In an apparatus forremoving sand-barsthe a chain is, as shown and described.

vessel A, having the well I), open at the under side and closed at the top, and the trunk B, projecting 011 an incline through said vessel, closed at the upper and open at the lower end,
